**An Elixir app which generates text-based tables for display**
Currently supports output:
* in customisable ASCII format.
* with your own renderer.
####Features
* A one-liner for those that just want to render ASCII tables with sane defaults.
* Support for table titles & alignable headers.
* Support for column & cell level alignment (center, left, right).
* Automatic cell padding but also the option to set padding per column<sup>1</sup>.
* Frame the table with various vertical & horizonal styles<sup>1</sup>.
* Style the table how you wish with custom separators<sup>1</sup>.
* Works well with the Agent module to allow for easy sharing of state.
* Clients can supply their own rendering modules and still take advantage of the table manipulation API.
<sup>1</sup> The text renderer supports these features, others may not or might not need to.
####Stability
This software is pre-v1 and therefore the public API *may* change; any breaking changes will be clearly
denoted in the [CHANGELOG](CHANGELOG.md). After v1, the API will be stable.
####Documenation
See the quick start below or check out the [full API docs at HexDocs](https://hexdocs.pm/table_rex/).
## Installation
The package is [available on Hex](https://hex.pm/packages/table_rex), therefore:
**Add** `table_rex` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:table_rex, "~> 0.3.0"}]
end
```
Then **start** `table_rex` by adding it to `application/0` in `mix.exs`:
```elixir
def application do
[applications: [:logger, :table_rex]]
end
```
##Quick Start
Use the `TableRex.quick_render` and `TableRex.quick_render!` functions; for those that just want a table quickly.
Given this data:
```elixir
title = "Drum & Bass Releases"
header = ["Artist", "Track", "Label", "Year"]
rows = [
["Konflict", "Cyanide", "Renegade Hardware", 1999],
["Marcus Intalex", "Temperance", "Soul:r", 2004],
["Kryptic Minds", "The Forgotten", "Defcom Records", 2007]
]
```
###TableRex.quick_render!/1
```elixir
rows
|> TableRex.quick_render!
|> IO.puts
```
```
+-----------------+---------------+-------------------+------+
| Konflict | Cyanide | Renegade Hardware | 1999 |
| Marcus Intalex | Temperance | Soul:r | 2004 |
| Kryptic Minds | The Forgotten | Defcom Records | 2007 |
+-----------------+---------------+-------------------+------+
```
###TableRex.quick_render!/2
```elixir
rows
|> TableRex.quick_render!(header)
|> IO.puts
```
```
+----------------+---------------+-------------------+------+
| Artist | Track | Label | Year |
+----------------+---------------+-------------------+------+
| Konflict | Cyanide | Renegade Hardware | 1999 |
| Marcus Intalex | Temperance | Soul:r | 2004 |
| Kryptic Minds | The Forgotten | Defcom Records | 2007 |
+----------------+---------------+-------------------+------+
```
###TableRex.quick_render!/3
```elixir
rows
|> TableRex.quick_render!(header, title)
|> IO.puts
```
```
+-----------------------------------------------------------+
| Drum & Bass Releases |
+----------------+---------------+-------------------+------+
| Artist | Track | Label | Year |
+----------------+---------------+-------------------+------+
| Konflict | Cyanide | Renegade Hardware | 1999 |
| Marcus Intalex | Temperance | Soul:r | 2004 |
| Kryptic Minds | The Forgotten | Defcom Records | 2007 |
+----------------+---------------+-------------------+------+
```
##Run the tests
We have an extensive test suite which helps showcase project usage. For example: the [quick render functions](https://github.com/djm/table_rex/blob/master/test/table_rex_test.exs),
[table manipulation API](https://github.com/djm/table_rex/blob/master/test/table_rex/table_test.exs) or [the text renderer module](https://github.com/djm/table_rex/blob/master/test/table_rex/renderer/text_test.exs).
To run the test suite, from the project directory, do:
```bash
mix test
```
